a while back I had posted about intermittent suction side air leaks that would cause our pump to lose prime. Hubby replaced the band connector seen in the upper right corner here:
with a threaded fitting and union so it looks like this now:
We also replaced the o-ring of the pump basket and things seemed to be looking good for about a week or so. Then yesterday afternoon I thought I'd run the pump a bit more b/c the water looked a little cloudy and I heard the unmistakable sound of a pump that lost prime. So I did the usual fill up the basket, add a bit more pool lube to the o ring, start pump and open bleed valve. The pump basket would fill up slowly and the PSI would go up but then before the water reached the lid, the PSI and water level would drop back down again.
Is this a sign of a dying pump?
If not, what could the problem be?
If yes, what pumps would you recommend for an IGP of about 18K gallons with one skimmer, one return, one vacuum inlet (and suction control valves that have probably been frozen in place for a decade or more, so that the only way to divert more suction to the skimmer or the vacuum is to block the vacuum port or skimmer port), and equipment as listed in my siggy? Thanks!
